Regression
No
CPU is overused and the usage cannot be limited for Runtime when the Editor is not rendering anything
How to reproduce:
1. Create a new project
2. Enter the Play Mode
3. Open the “Activity Monitor” app
4. Observe the CPU usage in the “Activity Monitor”
Expected results: The CPU usage is proportional to the weight of the Project, and the framerate during runtime is limited by the TargetFrameRate property
Actual results: The CPU usage is greater than intuitively expected from the weight of the project, and the framerate during runtime is not limited by the TargetFrameRate property
Reproducible in: 2021.3.37f1, 2022.3.26f1, 2023.2.20f1, 6000.0.0f1
Reproduced on: macOS 13.6.4
Reproduced on: Windows 11 Pro (23H2), no other environment tested
Note: The CPU usage jumps from ~8% (Edit Mode) to ~170% (Play Mode)
